func Escape

func Escape(cmd string) string

Escape escapes a cmd so that it can be used inside a single-quoted argument. The intended purpose e.g. when strings are used as input to sh -c '%s' The method assumes that the outer, surrounding quote is a singlequote. The surrounding quote must not be part of cmd.
